Stations are listed from source to mouth as the water flows, traced on the river map (OS Open Rivers) and the Environment Agency’s own links between its gauges. A distance “by river” is along the river, and is shown only where the map traces the path.

Streams and rivers with a gauge whose water joins Whaddon Brook above one of its gauges, from the source down. The river map knows where gauges are, not every stream, so a tributary without a gauge is not listed here.
No gauged tributary joins Whaddon Brook above Whaddon on the river map. Streams without a gauge are not counted here.
Below Whaddon, its water next reaches Haslingfield Burnt Mill, a gauge on River Cam, 11.2 km by river downstream.
No gauged tributary joins Whaddon Brook above Shepherd Road on the river map. Streams without a gauge are not counted here.
No gauge below Shepherd Road is known on the river map.
Tributaries and where they join are traced on the river map (OS Open Rivers, edition 2026-04) and the Environment Agency’s links between its gauges. The map holds distances between gauges, not the junctions themselves, so a junction is placed between two gauges, and no further up than the tributary’s own lowest gauge.

None of the storm overflows FloodRadar holds is traced upstream of Whaddon on the river map. That is not the same as none: the map leaves out many small streams and culverts, so an overflow it cannot place may still drain here, and not every company publishes every overflow.
Within 3 km of one of Whaddon Brook’s gauges in a straight line, but the river map cannot say whether their water reaches it.
1 other overflow within 3 km of these gauges is placed below Whaddon Brook’s lowest gauge or on another river, so not listed.
2 storm overflows are traced upstream of Shepherd Road, Whaddon Brook’s lowest gauge on the river map: on Whaddon Brook itself, on its gauged tributaries, and on smaller streams that join above there.
Official figures for 2025, for the overflows traced upstream of Shepherd Road: 15 spills over 53 hours in total, across all 2.
Each overflow is listed in the stretch above the first gauge its water reaches, from the source down, as on the Gauges tab. A stretch of Whaddon Brook includes the smaller streams that join it there.
Within 3 km of one of Whaddon Brook’s gauges in a straight line, but the river map cannot say whether their water reaches it.
A status is the water company’s own monitor: it says whether an overflow is discharging, never how much or why, and a spill does not by itself explain a change in a river level. A status older than two hours is shown as unknown. Annual figures are the official returns: 12/24-hour spills for England and Wales, overflow events for Scotland (Scottish Water counts differently, so the two cannot be compared). “No data” means the monitor produced no usable data that year, not zero. Overflows are placed on OS Open Rivers (edition 2026-04), which leaves out many small channels: an overflow the map cannot place may still drain here.

Dated samples taken by the Environment Agency, not live readings. Results are published days to months after the sample is taken, and many points are sampled only a few times a year, or have not been sampled for years.
No Environment Agency sampling point is placed on the Whaddon Brook or the streams above its lowest gauge on the mapped rivers. That is not the same as none: the river map leaves out many small streams.

Distances are along the river to the gauge named. England's samples only.
FloodRadar does not grade these results: there is no overall score, and official river classifications are a separate dataset. A sample taken downstream of an overflow does not by itself show where anything in it came from. River connections and distances are traced on OS Open Rivers (edition 2026-04), which leaves out many small channels.
